OUTLET-BOX AND FIXTURE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 562,633, dated June 23, 1896.

This finish is also applied to the exterior of the nipple a.

Two boxes may be placed back to back in opposite faces ofv a partition, as indicated in Fig. 3, and securely fastened together, each from the rear by the screw or bolt, as indicated.

W'hen it is desired to provide for passing a wire from one to the other of suchboxes, each is provided with one or more openings in its bottom, as shown, connected by passages in the partition. Aswill be seen, the means for fastening the box in position coincide with the hollow nipple a.

In Fig. 9 the box is shown supported in the ceiling, the wiring-tubes I) D entering from the rear, as shown in Fig. 11, where they are shown screwed therein. They may, however, be entered therein simply by slip-joints, as seen in Fig. 11a. In this case provision is made for a gas-pipe G, which is tapped into the rear of the boss a, while the outer end of the latter carries the combination-fixture, supported as before, from the bottom of the box. The top or face of the box is open where it is not covered in by the cover-plate, which latter, as already stated, is made with an opening around the fixture-pipe for drawing the wires. The finish is completed by the canopy', as shown. Then the box is supported by the gas-tube, as shown, and by the wiringtubes also, if desired, it is not necessary to extend the cover-plate into a flange and to fasten it independently of the box. The flange is shown in Fig. 8, but is dispensed with in Fig. 10.

The relative dimensions are indicated in Fig. 4. In this ligure I have also shown the preferred form of cover-plate. IVI H are ears or projections upon the cover which adapt the box for attachment of the ordinary rosette or cut-out block of porcelain or other material, from which may be supported a drop or other light. They also provide for attachment of a wall-socket or other lampreceptacle at outlets where the same may be desired.

Figs. 12 to 14 show the box as provided with an additional boss or opening adapted to receive a gas-pipe through the side of the box when the same is used in a side wall or partition. In this case an additional split or divided boss may be used similar to those already described. Fastened upon the base of the block is the gas-elbow I, which receives said pipe and carries also the gas and electric fixture. The box is here shown adapted for fixing in a side wall when it is not permissupporting structure.

As shown, an expansion-bolt is provided. This bolt passes through a removable bushing or plug L, in the bottom of the box at or about its center. The gas-elbow is fastened to the box over said plug. The plug is preferably square, Figs. 12, 13, and 14, to prevent it from turning in its seat, though it may be round, as indicated in Fig. 12% lVhen the box is used for an electric fixture, the plug may be replaced by an interchangeable plug, such as L', (indicated in Fig. 15,) which is formed with a nipple for attachment of the electric fixture. The head of the bolt is seated in the plug, as shown.

In all cases the box should be provided with the porcelain lining.

lVhat I claim as my invention is- 1. The combination with an outlet-box having a seat formed in the bottom thereof, of a removable bushing fitted to said seat, a bolt passing through said bushing for securing the box in place, and a gas-elbow removably secured to the back of the box over the bushing-seat.

2. An outlet-box having openings for fixture-tubes and wiring-tubes and having a screw-threaded nipple formed integrally with the box and projecting inwardly from its bottom for the attachment of the fixture-tube, a hole being formed in the center of said nipple for receiving the device for securing the box in place.

3. An electric-wiring outlet-box having a removable cover provided with a flange projecting beyond the box by which the cover may be fastened directly to the wall or c eiling, as and for the purpose described.

4. The combination with an outlet-box having a seat formed in the bottom thereof, of a removable bushing iitted to said seat, and a bolt passing through said bushing for securing the box in place.

5. The combination with an outlet-box having a seat formed in the bottom thereof, of a removable bushing fitted to said seat and having a nipple formed integral therewith for the attachment of a xture, and a bolt passing through said bushing for securing the box and fixture in place.

The combination with an electric-wiring outlet-box, provided with a number of split bosses or sockets the halves of' which are formed respectively upon the box and its cover for the reception of wiring-tubes, of a plug having flanges upon both ends and fitted to said bosses, as and for the purpose set forth.

7. A ceiling outlet-box having openings for fixture-tubes and wiring-tubes and having an internally-screw-threaded nipple integral with its bottom to receive a gas-pipe in one end to hold the box in place and to receive a fixture in the other end and having projections upon the nipple to limit the insertion of and to support wiring-tubes. sible to attach from the opposite side of the York and State of New York, this 13th day Signed at New York, in the county of New of February, A. D. 1895.
